abstract = "We investigated how indexed FOR-loops, such as the
ones found in procedural programming languages, can be
implemented in genetic programming. We use them to
train programs that learn the repeating unit string of
a given regular binary pattern string and can reproduce
the learnt pattern to an arbitrary size, specified by a
parameter N. We discovered that this particular
problem, where the solution needs to scale with
multiple size-instances of the problem, is very hard to
solve without the help of domain knowledge.",
